-
#delete_document(options = {}) ⇒ Hash
Deletes the model instance from the index.
-
#index_document(options = {}) ⇒ Hash
Serializes the model instance into JSON (by calling ‘as_indexed_json`), and saves the document into the Elasticsearch index.
-
#update_document(options = {}) ⇒ Hash
Tries to gather the changed attributes of a model instance (via [ActiveModel::Dirty](api.rubyonrails.org/classes/ActiveModel/Dirty.html)), performing a partial update of the document.
-
#update_document_attributes(attributes, options = {}) ⇒ Hash
Perform a partial update of specific document attributes (without consideration for changed attributes as in #update_document).

#update_document(options = {}) ⇒ Hash
Tries to gather the changed attributes of a model instance (via [ActiveModel::Dirty](api.rubyonrails.org/classes/ActiveModel/Dirty.html)), performing a partial update of the document.
When the changed attributes are not available, performs full re-index of the record.
See the #update_document_attributes method for updating specific attributes directly.
